Engaging parents to promote girls\u27 transition to secondary education: Evidence from a cluster randomised trial in rural Gujarat, India

The Population Council and partners, with the support of the Human Dignity Foundation and the John D. and Catherine T. MacArthur Foundation, implemented a pilot intervention in India─Project Sankalp─to assess the acceptability and feasibility of engaging parents and communities to promote girls’ secondary education. The project\u27s aim was to measure its effectiveness in improving adolescent girls’ transition to secondary education, their attendance at school, and learning outcomes. Findings show that the effect of Project Sankalp on creating an enabling environment for girls to pursue secondary education was mixed. On the positive side, the project showed success in raising girls’ educational aspirations; improving parental support for their secondary education; and raising girls’ awareness of school management committees. However, there was no evidence of any effect on girls’ agency in matters concerning their schooling, awareness and utilization of the benefits available from school, and the time committed to school-related activities. These findings underscore the need for a longer-term engagement with girls and their parents than was possible in Project Sankalp, or for more intensive efforts that will enable girls to make effective use of the knowledge and skills they gain, and give parents more time to translate the messages they receive into real life practices

Antioxidant Therapy Does Not Reduce Pain in Patients with Chronic Pancreatitis: The ANTICIPATE Study

Background & Aims: We investigated whether antioxidant therapy reduces pain and improves quality of life in patients with chronic pancreatitis. Methods: We performed a double-blind, randomized, controlled trial that compared the effects of antioxidant therapy with placebo in 70 patients with chronic pancreatitis. Patients provided 1 month of baseline data and were followed up for 6 months while receiving either Antox version 1.2 (Pharma Nord, Morpeth, UK) or matched placebo (2 tablets, 3 times/d). The primary analysis was baseline-adjusted change in pain score at 6 months, assessed by an 11-point numeric rating scale. Secondary analyses included alternative analyses of clinic and diary pain scores, scores on quality-of-life tests (the EORTC-QLQ-C30, QLQ-PAN28, EuroQOL EQ-5D, and EQ visual analog score), levels of antioxidants, use of opiates, and adverse events. Analyses, reported by intention to treat, were prospectively protocol-defined. Results: After 6 months, pain scores reported to the clinic were reduced by 1.97 from baseline in the placebo group and by 2.33 in the antioxidant group but were similar between groups (−0.36; 95% confidence interval, −1.44 to 0.72; P = .509). Average daily pain scores from diaries were also similar (3.05 for the placebo group, 2.93 for the antioxidant group, a difference of 0.11; 95% confidence interval, 1.05–0.82; P = .808). Measures of quality of life were similar between groups, as was opiate use and number of hospital admissions and outpatient visits. Blood levels of vitamin C and E, β-carotene, and selenium were increased significantly in the antioxidant group. Conclusi1ons: In patients with painful chronic pancreatitis of predominantly alcoholic origin, antioxidant therapy did not reduce pain or improve quality of life, despite causing a sustained increase in blood levels of antioxidants.

Supporting girls in their transition to secondary education: An exploratory study of the family, school and community environments of adolescent girls in Gujarat

Despite government commitment to universal secondary education in India, few adolescents transition to and successfully complete secondary education. In India, limited efforts have been directed at parents to promote positive attitudes toward education and school completion. Recognizing the need for identifying effective intervention strategies to engage parents and communities to promote secondary education for girls, the Population Council and partners are pilot-testing an intervention to support adolescent girls’ transition to and retention in secondary education. Located in the state of Gujarat, the intervention focuses on girls in the last year of primary school and first year of secondary school and their parents as well as teachers and the wider community. The school experiences of adolescent girls, and the family, school, and community environments in which they are pursuing their studies, described in this report, draw on a baseline survey conducted in 90 villages in Gujarat. The objective was to explore school experiences of adolescent girls in the last year of primary and first year of secondary school, and assess the extent to which a supportive environment for schooling was available to them at the family, school, and community levels

Petrophysical evaluation and uncertainty analysis of Roseneath and Murteree shales reservoirs in Cooper Basin, Australia (a case study)

This study investigates petrophysical characteristics of lacustrine Permian Murteree and Roseneath shales in relation to reservoir evaluation of the most prospective gas shale plays in the Cooper Basin, Australia. Both shales were investigated for gas volumes by employing unconventional petrophysical techniques through a combination of source rock parameters acquired by geochemical analysis, and integrating the extracted parameters into log interpretation and core studies. Modeling mineralogical composition using wireline logs require the selection of a proper mineral model. In this study, the mineral model was built in the Interactive Petrophysics (IP's) Mineral Solver module by integrating all regional sedimentological, petrographic, SEM (Scanning electronic microscope), pulse decay and X-ray diffraction data (XRD) from core and chip cutting samples. This study developed a mineral grouping framework to assist in the selection of a proper model to easily solve complex shale gas reservoirs for gas volumes. Furthermore, the permeability of both shales depends on in-situ confining stress and permeability of these cores and can be calculated through decay rate of a pressure pulse applied to experimental data. Subsequent to the integrated study as explained above, it is concluded on the basis of extruded parameters (shale porosity, permeability, volume of kerogen, volume of brittle minerals and water saturation) that Murteree formation exhibits better potential than Roseneath formation in and around Nappameri, Patchawarra and Tenappera troughs, while poor potential is exhibited in the Allunga trough. The only location where Roseneath exhibits better potential is in Encounter-01 well

Association of psychosocial factors with short-term resting heart rate variability: The atherosclerosis risk in communities study

BACKGROUND: Psychosocial factors predict heart disease risk, but our understanding of underlying mechanisms is limited. We sought to evaluate the physiologic correlates of psychosocial factors by measuring their relationships with heart rate variability (HRV), a measure of autonomic health, in the ARIC (Atherosclerosis Risk in Communities) study. We hypothesize that increased psychosocial stress associates with lower HRV. METHODS AND RESULTS: We studied 9331 participants in ARIC with short-term HRV data at visits 2 and 4. The mean (SD) age was 54.4 (5.7) years, 55% were women, and 25% were Black. Psychosocial factors included: (1) vital exhaustion (VE), (2) anger proneness, a personality trait, and (3) perceived social support. Linear models adjusted for sociodemographic and cardiovascular risk factors. Low frequency HRV (ln ms2) was significantly lower in the highest versus lowest quartiles of VE (B=−0.14, 95% CI, −0.24 to −0.05). When comparing this effect to age (B=−0.04, 95% CI, −0.05 to −0.04), the difference was equivalent to 3.8 years of accelerated aging. Perceived social support associated with lower time-domain HRV. High VE (versus low VE) also associated with greater decreases in low frequency over time, and both anger and VE associated with greater increases in resting heart rate over time. Survival analyses were performed with Cox models, and no evidence was found that HRV ex-plains the excess risk found with high VE and low perceived social support. CONCLUSIONS: Vital exhaustion, and to a lesser extent anger and social support, were associated with worse autonomic function and greater adverse changes over time

Application of the scattering rate sum-rule to the interplane optical conductivity of high temperature superconductors: pseudogap and bi-layer effects

We use a recently proposed model of the interplane conductivity of high temperature superconductors to investigate the `scattering rate sum-rule' introduced by Basov and co-workers. We present a new derivation of the sum-rule. The quantal and thermal fluctuations of the order parameter which have been argued to produce the observed pseudogap behavior are shown to increase the total integrated `scattering rate' but may either increase or decrease the `quasiparticle' contribution from frequencies greater than twice the superconducting gap.Comment: 4 pages, 5 figures, revise

Synthesis of titanate nanofibers co-sensitized with ZnS and Bi2S3 nanocrystallites and their application on pollutants removal

The synthesis of nanocomposite materials combining titanate nanofibers (TNF) with nanocrystalline ZnS and Bi2S3 semiconductors is described in this work. The TNF were produced via hydrothermal synthesis and sensitized with the semiconductor nanoparticles, through a single-source precursor decomposition method. ZnS and Bi2S3 nanoparticles were successfully grown onto the TNF's surface and Bi2S3-ZnS/TNF nanocomposite materials with different layouts were obtained using either a layer-by-layer or a co-sensitization approach. The samples' photocatalytic performance was first evaluated through the production of the hydroxyl radical using terephthalic acid as probe molecule. All the tested samples show photocatalytic ability for the production of this oxidizing species. Afterwards, the samples were investigated for the removal of methylene blue. The nanocomposite materials with best adsorption ability for the organic dye were the ZnS/TNF and Bi2S3ZnS/TNF. The removal of the methylene blue was systematically studied, and the most promising results were obtained considering a sequential combination of an adsorption-photocatalytic degradation process using the Bi2S3ZnS/TNF powder as a highly adsorbent and photocatalyst material.Comment: 26 pages, 10 figure
